Hi guys! Okay, so I'm 17 years old (female), 5'1", and currently about 87-88 lbs. I am a cross country runner, and since it's off season I only have been running maybe 2-3 days per week (4-6 miles each time i run usually). I've recently started seeing a trainer at the gym 2x a week, but we haven't really been doing much yet--just foundational stuff really. I'm trying to gain more muscle, but I'm terrified of getting "fatter." I met with a nutrition coach at the gym and she gave me a meal plan to follow, but it seems like SO much food and SO much protein. They are also pressing me to drink protein shakes as well. But the problem is I feel like by eating all of this food and this amount of protein, I'm definitely going to gain fat and not just muscle because my working out is definitely not very intense. An example of a meal plan she gave me for a day is as follows:

Breakfast

2 slices whole grain bread

1 large orange

1 cup plain greek yogurt 0%

1 whole egg + 2 egg whites

Snack

Small apple

2 string cheeses

Lunch

2 slices whole wheat bread

2 slices lean deli meat

salad with 2 whole eggs

small fruit

Snack:

1/2 cup cottage cheese

small apple

1 cup almond milk

Lunch:

2 heaping serving spoonfuls of pasta with sauce

1 cup veggies

Snack:

1 cup plain greek yogurt with fruit

Popcorn

oh and she said my minimum caloric intake should be around 2200 which i feel is very high..

i'm also concerned about the weight gain too because i used to be slightly chubby and shed off those pounds last summer and i really don't want to gain that back.

I looked at your plan.
For the sake of your health, follow it as you need enough nutrition at your age.. As it is, you are quite thin for a woman of your age.
As long as you are active the calories won't matter.
Active people eat whatever they want without ill effects.

You need to gain a little wait so that you can burn it off to form muscles.

Don't worry about it. Your trainer knows what he is doing, it's his job to know.

Oh and 87-88 pounds is on the side of being a little to thin for a 5'1" girl.
